Serverless File Uploads

This tutorial teaches how to build a secure, serverless file upload system using the AWS Node.js runtime and the Serverless Framework. It aims to allow users to upload files directly to Amazon S3 without consuming any application server resources. The system uses an API endpoint that validates requests and returns a signed URL for direct-to-S3 uploads. This approach provides a scalable, reliable, and fast solution for file uploads while ensuring security and control over the uploaded files.
